Syncope forms a major part of medical in-flight emergencies contributing one-infour in-flight medical events accounting to 70%of flight diversions.In such patients,it is important to elucidate the pathophysiology of syncope prior to diversion.Postural hypotension is the most common etiology of in-flight syncopal events.However,individuals without any underlying autonomic dysfunction can still experience syncope from hypoxia also known as airline syncope.Initial steps in managing such patients include positioning followed by the airway,breathing and circulation of resuscitation.These interventions need to be in close coordination with ground control to determine decision for flight diversion.Interventions which have been tried for prevention include mental challenge and increased salt and fluid intake.The current paper enhances the understanding of airline syncope by summarizing the associated pathophysiologic mechanisms and the management medical personnel can initiate with limited resources.
Syncope forms a major part of medical in-flight emergencies contributing one-in-four in-flight medical events accounting to 70% of flight diversions. In such patients, it is important to elucidate the pathophysiology of syncope prior to diversion. Postural hypotension is the most common etiology of in-flight syncopal events. However, individuals without any underlying autonomic dysfunction can still experience syncope from hypoxia also known as airline syncope. Initial steps in managing such patients include positioning followed by the airway, breathing and circulation of resuscitation. These interventions need to be in close coordination with ground control to determine decision for flight diversion. Interventions which have been tried for prevention include mental challenge and increased salt and fluid intake. The current paper enhances the understanding of airline syncope by summarizing the associated pathophysiologic mechanisms and the management medical personnel can initiate with limited resources.
